Document Summary
One breath is a full cycle of inspiration and expiration. Inspiration: breathing in, chest expands, diaphragm contracts. Expiration: breathing out, chest contracts, diaphragm relaxes. Of importance: suprasternal notch, manubirum of sternum, manubriosternal angle, cosochondral junction, xiphoid process, costal angle (<90 ), and ribs 2,4,5,6. Of importance: there are 12 vertebra (start with the prominent c7 and count down), 12th rib, inferior angle of scapula, spinous process of t3, 10, and 12. Scapular line (lines up with where scapula starts) * also mid-axillary line on side of chest. The lungs are composed of lobes that are joined together at fissures. The right lung has 3 lobes but is smaller (since the liver is below it) and the left lung has 2 lobes and is slightly offset (the heart pushes it to the left). Note that the upper lobes are heard when auscultating anteriorly and the lower lobes are heard when auscultating posteriorly.
